To the Editor: In their meta-analysis of the effectiveness of LTPP, Drs Leichsenring and Rabung1 concluded that LTPP was significantly superior to shorter-term methods of psychotherapy with regard to overall outcome, target problems, and personality functioning. There are multiple problems with their meta-analysis that mitigate the scientific credibility of this conclusion.
